The USA Hockey rule book does not give a specific length, it only states that periods can not be longer than 20 minutes. So it will depend on the level (whether it is rec or travel) and the location of the game. Each state/local affiliate will have their own rules. It will also depend on whether it is a running time or stop time game.
From my experience, with an hour long time slot, Mites will normally play 10-12 minute stop time periods or 15 minute running time periods.
Stop time games will also sometimes determine the length of the 3rd period based on how much time is left on the curfew. For example a "12/12/half" game would have 12 minutes for the 1st and 2nd period and then the 3rd period would be half of the time remaining on the ice curfew.
periods in a high school ice hockey game are generally 12-14 minutes in length

The first of 3 even amounts of time in a hockey game. Hockey has 3 periods per game. It is usually called the 1st period, not period one. Technically an overtime counts is a period, which means games can have an unlimited number of periods. I think the record for an NHL game is 6 overtimes, or 9 periods.
If you mean enter a hockey game in the arena, then yes. why you dont want to see the first two periods is your choice

Three 20-minute periods are in a regulation Hockey game, and a possible 5-minute to 20-minute overtime.
Third period starts 40 minutes into the game and lasts 20 minutes.
